Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a packaged product. More specifically, it comprises a container capable of opening and closing and accumulating pressure, and a water-soluble polymer capsule sealed with a gas generating substance and water sealed in the container. The present invention relates to a packaged product in which a gas is generated by contacting and dissolving with water to generate a gas and discharging the content using the generated gas as a pressurizing agent.

2. Description of the Related Art Products in the form of discharge include aerosol products and pump products. In an aerosol product, a stock solution containing an active ingredient and a propellant (a liquefied gas such as LPG and DME and a compressed gas such as nitrogen and carbon dioxide) are filled in a pressure-resistant container and sealed. Then, by opening a valve attached to the container body, the contents are discharged in a state of fog, foam, gel, or the like. Aerosol products have good sealing properties, excellent operability,
The use of a liquefied gas has the advantage that excellent spraying characteristics (fineness of fog, stability of foam, cooling effect, etc.) can be obtained.

[0003] However, aerosol products have problems that they cannot be refilled, and that since most of them are metal containers, it takes time to dispose of the gas after use.

On the other hand, in the case of a pump product, it is easy to refill the container, but the pump itself is large and it is difficult to reduce the size. Also, since the content itself does not have pressure,
There is a problem that it is necessary to accumulate pressure until discharge is possible, and the pump must be operated many times before discharging.

[0005]

And a valve 4 (the valve 4 is composed of a tiltable valve stem 5, a holding portion 6 and a packing 7), and each component is preferably made of a non-metallic material because it can be heated by microwaves and can be discarded separately. . For example, as the container body 2, a glass bottle, a plastic bottle, or the like is preferably used because the contents are transparent and the contents can be seen, so that the dissolution of the encapsulated substance can be confirmed. A metal container such as aluminum or tin may be used in consideration of pressure resistance. The cap 3 is made of a resin such as nylon or Duracon, and has a valve stem insertion opening 3a opened on the upper surface thereof. The lower end inner surface has a portion for fitting with a screw fitting portion provided on the neck portion 2b of the container body 2, and can be easily closed. The valve stem 5 is made of a resin such as nylon or Duracon, and is attached to the cap 3 so as to be tiltable by engaging a ring-shaped flange portion 5a with a collar receiving portion 3b of the cap 3.

The injection button 13 is attached to the valve stem 17a of the lid member 12. When the injection button 13 is pressed down, the valve stem 17a moves downward, the valve seal 17c bends, and the seal between the upstream opening 17b and the valve seal 17c is closed. Because it is released, the contents are ejected. In addition, in FIG. 2, 19 shows a liquid level.

The amount of the contents in the container which can be opened and closed and accumulates is 40 to 90% of the internal volume, more preferably 50 to 8%.

As shown in FIG. 5, the product is put into a container main body 24 of a valve-equipped container (resin container (full filling amount: 40 ml)) that can be opened and closed, and a valve-attached lid 25 is attached to form a packaged product (freshener) I got

The product was shaken gently to dissolve the water-soluble polymer capsule and the powder in the capsule, and was left for a while (about 1 minute) after dissolution. The obtained contents are gel-like,
The product pressure was 0.5 MPa (gauge pressure) (25 ° C.). When the spout was attached and the valve was opened, it was discharged as a foam.

Examples 2 to 6 Various packaging products were obtained in the same manner as in Example 1 except that the gas generating substances, active ingredients and aqueous stock solutions shown in Table 1 were used. Table 1 shows the pressure (gauge pressure) of the obtained product at 25 ° C., the properties of the contents, and the discharge state when the spout was attached and the valve was opened.

According to the present invention, it is possible to prepare a packaged product which can be easily discharged by using the encapsulated material when necessary, so that there is no fear of decay of the contents, and a container which can be opened / closed and pressure-accumulated is used. Therefore, it can be prepared repeatedly as many times as possible, without wasting the container, furthermore, the container can be miniaturized, it can be easily carried, the storage space can be reduced, and because of its viscosity, It is possible to obtain a packaged product in which the liquid dripping hardly occurs.
